WNetCancelConnection
The WNetCancelConnection function breaks an existing network connection.
The function is provided for compatibility with earlier versions of Microsoft
Windows. For new applications, use the WNetCancelConnection2 function.
DWORD WNetCancelConnection(
LPTSTR lpName,
| // pointer to resource name to be disconnected
| BOOL fForce
| // flag for unconditional disconnect
| );
|
|
Parameters
lpName
Points to a null-terminated string that specifies the name of either the
redirected local device or the remote network resource to disconnect from. When this
parameter specifies a redirected local device, only the specified device
redirection is broken. If the parameter specifies a remote network resource, only
the connections to remote networks without devices are broken.
fForce
Specifies whether the disconnection is to occur even if there are open files
or jobs on the connection. If this parameter is FALSE, the function fails if
there are open files or jobs.
Return Values
If the function succeeds, the return value is NO_ERROR.
If the function fails, the return value is an error code. To get extended
error information, call GetLastError. GetLastError may return one of the following error codes:
Value
| Meaning
| ERROR_BAD_PROFILE
| The user profile is in an incorrect format.
| ERROR_CANNOT_OPEN_PROFILE
| The system is unable to open the user profile to process persistent
connections.
| ERROR_DEVICE_IN_USE
| The device is in use by an active process and cannot be disconnected.
| ERROR_EXTENDED_ERROR
| A network-specific error occurred. To get a description of the error, use the WNetGetLastError function.
| ERROR_NOT_CONNECTED
| The name specified by the lpName parameter is not a redirected device, or the system is not currently
connected to the device specified by the parameter.
| ERROR_OPEN_FILES
| There are open files, and the fForce parameter is FALSE.
|
The function returns error codes for compatibility with Windows version 3.1.
For compatibility with the Win32 API, the function also sets the error code
value returned by GetLastError.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
